Key result
Melting / freezing pt.:
28.2 °C
Conclusions:
melting point = 28.2°C
Executive summary:

According to the CRC Handbook of Chemistry and Physics (and Lange's Handbook of Chemistry respectively), the melting point of Octadecane is 28.2°C.

No further details are reported in the handbooks on the determination. Reported value is assumed to have been determined at STP (20°C, 101.3 kPa).

Conclusions:
melting point = 28°C
Executive summary:

According to Perry's Chemical Engineer's Handbook, the melting point of Octadecane is 28°C.

No further details are reported in the handbook on the determination. Reported value is assumed to have been determined at STP (20°C, 101.3 kPa).

Description of key information

1) 26-28°C (Shell, 2014)

2) 28.2°C (CRC Handbook, 2005; Lange's Handbook of Chemistry, 1999)

3) 28°C (Perry`s Chemical Engineers`Handbook, 1999)

Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:
28 °C

Additional information

An experimentally derived value is available for Octadecane, using ASTM method E793 (Shell, 2014). Further two values obtained are from literature sources with no specific details of methodology.

The available information is consistent and provides sufficient data to allow a reliable result to be determined.
